        </h2>
        <p>
          <span class="application">Vala</span> is a new programming language
          that aims to bring modern programming language features to
          <span class="application">GNOME</span> developers without imposing
          any additional runtime requirements and without using a different
          ABI compared to applications and libraries written in C.
        </p>
        <p>
          This package is known to build and work properly using an LFS-9.1
          platform.
